Rationalizing functions to identify re-usable services

ABSTRACT

A method of dynamically offering upgraded services in a network comprising functions, the method comprising a computer performing the steps of: applying a similar functionality analysis on the functions of a network; retrieving the plurality of functions stored by the similar functionality analysis from the repository, and creating a pivot table; categorizing the functions within the pivot table; filtering the pivot table by a functional area of the pivot table; recreating the pivot table based on the functional area; and differentiating the exposable functions within the pivot table from non-exposable functions by attributes of the functions.

BACKGROUND

The present invention relates to services, and more specifically to rationalizing functions to identify re-usable services.

Service Oriented Architecture (SOA) solutions are business process driven and are required to support business functions in various functional areas. A functional area is a logical grouping of related or cohesive functions. Key objectives of SOA are identification and design of services which are re-usable and flexible to accommodate variations that a business must support in order to be agile. In a medium to large size SOA projects, normally there are different teams who are assigned specific business processes and functional areas to analyze with the intent to identify re-usable and flexible services (i.e. services which can support variations). In this distributed work environment, analysis often results in duplicate functions being identified by various teams. If the number of functional areas is large there is a potential for significant amount of duplication. If there is no mechanism or technique to identify and consolidate or eliminate these duplicate functions, a large number of candidate services that support or perform same functions are identified.

The focus in SOA is on identifying services that need to be exposed. A service modeling toolkit such as IBM's SOMA-ME-Service Oriented Modeling Architecture Modeling Environment, is used to rationalize which services need to be exposed and which should not be exposed to consumers within and outside of an enterprise. The toolkit, though it automates the process of prioritizing and ranking services to help decide which services to be exposed, it still requires business and IT team members to apply every question (in the toolkit) and associated scores to each and every candidate service. This can take a significant amount of time if the number of candidate services is large (i.e. candidate services >500) due to duplication.

DETAILED DESCRIPTION

FIG. 1 is an exemplary diagram of a possible data processing environment provided in which illustrative embodiments may be implemented. It should be appreciated that FIG. 1 is only exemplary and is not intended to assert or imply any limitation with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environments may be made.

Referring to FIG. 1, network data processing system 51 is a network of computers in which illustrative embodiments may be implemented. Network data processing system 51 contains network 50, which is the medium used to provide communication links between various devices and computers connected together within network data processing system 51. Network 50 may include connections, such as wire, wireless communication links, or fiber optic cables.

In the depicted example, a client computer 52, server computer 54, and a repository 53 connect to network 50. In other exemplary embodiments, network data processing system 51 may include additional client computers, storage devices, server computers, and other devices not shown. The client computer 52 includes a set of internal components 800 a and a set of external components 900 a, further illustrated in FIG. 24 The client computer 52 may be, for example, a mobile device, a cell phone, a personal digital assistant, a netbook, a laptop computer, a tablet computer, a desktop computer, a sequencing machine or any other type of computing device.

Client computer 52 may also contain an interface 72. The interface can be, for example, a command line interface, a graphical user interface (GUI), or a web user interface (WUI). The interface may be used, for example for viewing a pivot table, the similar function analysis, or the exposable functions or candidate services.

In the depicted example, server computer 54 provides information, such as boot files, operating system images, and applications to client computer 52. Server computer 54 can compute the information locally or extract the information from other computers on network 50. Server computer 54 includes a set of internal components 800 b and a set of external components 900 b illustrated in FIG. 24.

Program code and programs such as a pivot table creator program 67, an exposable functions program 68, and/or a similar functionality analysis program 66 may be stored on at least one of one or more computer-readable tangible storage devices 830 shown in FIG. 24, on at least one of one or more portable computer-readable tangible storage devices 936 as shown in FIG. 24, or repository 53 connected to network 50, or downloaded to a data processing system or other device for use. For example, program code, a pivot table creator program 67, an exposable functions program 68, and/or a similar functionality analysis program 66 may be stored on at least one of one or more tangible storage devices 830 on server computer 54 and downloaded to client computer 52 over network 50 for use on client computer 52. Alternatively, server computer 54 can be a web server, and the program code and programs such as a pivot table creator program 67, an exposable functions program 68, and/or a similar functionality analysis program 66 may be stored on at least one of the one or more tangible storage devices 830 on server computer 54 and accessed on client computer 52. A pivot table creator program 67, an exposable functions program 68, and/or a similar functionality analysis program 66, can be accessed on client computer 52 through interface 72. In other exemplary embodiments, the program code, and programs such as a pivot table creator program 67, an exposable functions program 68, and/or a similar functionality analysis program 66 may be stored on at least one of one or more computer-readable tangible storage devices 830 on client computer 52 or distributed between two or more servers.

In the depicted example, network data processing system 51 is a combination of a number of computers and servers, with network 50 representing the Internet—a worldwide collection of networks and gateways that use the Transmission Control Protocol/Internet Protocol (TCP/IP) suite of protocols to communicate with one another. At the heart of the Internet is a backbone of high-speed data communication lines between major nodes or host computers, consisting of thousands of commercial, governmental, educational and other computer systems that route data and messages. Of course, network data processing system 51 also may be implemented as a number of different types of networks, such as, for example, an intranet, local area network (LAN), or a wide area network (WAN). FIG. 1 is intended as an example, and not as an architectural limitation, for the different illustrative embodiments.

In an embodiment of the present invention, the method of rationalizing functions to identify re-usable services to filter functions or candidate services prior to the usage of service modeling toolkit can filter out 75 to 90 percent of the functions or candidate services for entry into the service modeling toolkit. To the reduced number of functions or candidate services, a service litmus test to identify services that need to be exposed across Lines of Business (LoB), across client enterprise and/or third party may be applied.

Candidate services are groups of functions that have been previously identified. Functions are potential candidate services. All functions or candidate services have at least a description, which helps to differentiate one function from the other. The function description preferably includes attributes such as a specific action and the object on which this action is performed.

The method of the present invention may be implemented through spreadsheet tools to minimize manual and time consuming effort, through paper; or through an Eclipse or Windows based tool. With implementation through an Eclipse or Windows based tool, an automated lexical analysis may be used to suggest duplication; re-use in different case scenarios, and calculating function or candidate service complexity. The automated lexical analysis may be carried out through the usage of string functions in C/C++ or Java platform to define a list of key words to perform custom lexical analysis or through the usage of lexical generators such as JavaCC, JFlex, JLex in the Java platform and Flex or Quex in the C/C++ platform. It should be noted that data mining may be used to determine similarities between function names and description, whether function names are compliant, using proper patterns, whether a function may be used a façade and whether functions should be classified as services, functions, or removed. The data mining may be carried out by a program, such as DB2 Intelligent Miner produced by International Business Machines Corporation. Data mining is the process of automatically searching large volumes of data for patterns. Data mining may be further defined as the nontrivial extraction of implicit, previously unknown, and potentially useful information from data. Data mining may use computational techniques from statistics, information theory, machine learning, and pattern recognition.

FIGS. 2-7 show a flowchart of a method of rationalizing functions to identify re-usable services. A similar functionality analysis is applied to functions of a service oriented architecture (SOA) to remove duplications, unify functions, and ensure function or candidate service connections, for example through the similar functionality analysis program 66.

The unified functions resultant from analysis are stored in a repository (step 101). The repository may be repository 53 shown in FIG. 1. Unified functions are functions that have been rationalized and combined based on their description, which indicates that the functions perform similar capabilities with only slight variations. The similar functionality analysis removes duplications and ensures function or candidate service connections by: identifying functions with similar names and identical functionality; identifying functions with similar names but different functionality to eliminate all duplication functions using function description as a basis; identifying functions with different names, but identical functionality to group functions with some variations in functionality, but with overlapping commonality under a course grained façade function; ensure function name and description for correctness by accepting, deleting, or fixing; and related functions to façades. Once the similar functionality analysis is complete, the analysis may include: the function/candidate name, function description; action resulting from analysis of accepted, added, deleted, or unified; the unified function name, and the façade for a course grained function that can be supported by finer grained functions, for example as shown in FIGS. 10-13. Step 101 is further described in FIGS. 3-5.

The functions resultant from the similar functionality analysis are retrieved from the repository and a pivot table is created with the unified functions (step 102), for example by the pivot table creator program 67. The functions within the pivot table are categorized (step 103). The categorization includes categorizing based on operation the function or candidate service performs through create, read, update, delete, technical functions, and wrongly placed (CRUDTW) operations, the functional area the candidate service or function should belong to and the business activity type. The categorization is preferably based on the function or candidate service description.

FIG. 13 shows an example of adding all functions or candidate services which actions are catalogued as “added” or “accepted” in a similar functional analysis (step 103). The pivot table allows each function to be catalogued as a CRUDTW operation, business type and function area to which it belongs. CRUDTW operations includes a create (C) operation, a read (R) operation, an update (U) operation, a delete (D) operation, a technical (T) operation, and a wrong (W) placed operation. In one embodiment, the pivot table includes function/candidate service name, CRUDTW operation; functional area business type activity; and function type. The function type includes functional (e.g. business function); information (e.g. information access/updates and functions that support business functions); and utility (e.g. technical functions such as send notification).

FIG. 14 shows an example of functions or candidate services being categorized within a pivot table. Technical functions, such as “send notification” would be flagged as a “T” and any function that is wrongly placed in a functional area would be flagged as a “W” and moved to an appropriate functional area. Additionally, the activity type functions may also be categorized.

The pivot table is then filtered by functional area (step 104). FIG. 15 shows an example of generating a table by selecting functions or candidate services belonging to a particular functional area. In this example, the functional area filter is auditing management.

An updated pivot table is then recreated based on functional area (step 105). FIG. 16 shows an example of selecting all rows for creating another or an updated pivot table. It should be noted that in most cases, functions catalogued as Information Services will be filtered since they are not considered to be exposable in most projects and were filtered out when the generating and filtering by the functional area.

The exposable functions or candidate services are then differentiated from non-exposable functions or candidate services by function attributes (step 106) through functional area rationalization, for example by the exposable functions program 68. Exposable functions or candidate services are those which have more than one consumer and need to have standardized way of being invoked i.e. require standardized interface. Exposable functions are determined through functional area rationalization as discussed relative to FIGS. 20, 21 and 22. The functional area rationalization includes identification of use cases related to the function, identification of function re-use across different use scenarios, determination of complexity level based on the number of user interfaces to determine effort required to implement these candidate services or functions. More specifically, the functional area rationalization includes information from the pivot table, the use case name associated with the function, the analysis linked to the function, the function/service analysis results, use case scope within a project, the number of cases related to the function for re-use identification, service name to be used in litmus test for service exposure decisions, identified pattern to follow function for identifying level of granularity; complexity of function to qualify initial implementation effort; number of user interfaces linked to the function for re-use identification and dependencies. To use the recreated pivot table, the pivot table is preferably organized by order of importance. In one embodiment, the selected order of importance is Functional Area, CRUDTW, Business Type, and Function, for example as shown in FIGS. 17 and 19. The fields selected are selected in order from highest to lowest in importance. Step 106 is further described in FIGS. 6-7.

The results of the differentiation of exposable function services through functional area rationalization are captured for access by a service modeling toolkit to evaluate candidate service for exposure decisions (step 107) such as IBM's SOMA-ME-Service Oriented Modeling Architecture Modeling Environment. FIG. 23 shows an example of the captured results in an SOMA-Me toolkit to evaluate candidate service for exposure decisions.

FIGS. 3-5 show increased detail of step 102 of FIG. 1 of applying a similar functionality analysis to functions to remove duplication and ensure function connections.

Referring to FIG. 3, candidate services or functions including function name and description are retrieved (step 108), for example from a repository, such as repository 53 shown in FIG. 1 by the similar functionality analysis program 66. An example of candidate services or functions resultant from a similar functionality analysis and functions descriptions received by similar functionality analysis are shown in FIG. 8. If the function name of a function is the same or similar the function name of another function (step 109), determine if the functional description of the function is similar to the functional description of another function (step 110). FIG. 9 shows an example of unifying functions or candidate services by looking for similar or synonymous verbs/nouns and descriptions to identify duplicates.

If the functional description of a function is similar to the functional description of another function (step 110), combine the function under a common function name usable to represent the functions under consideration (step 112) , and unify all functions to the common name and store the common name and function descriptions in a repository (step 114), for example repository 53 shown in FIG. 1 and continue to step 103 of retrieving functions resultant from the similar functionality analysis and create a pivot table.

If there is not a common function name usable to all functions under consideration (step 112), add a new function name and unify all functions to the new name and store in a repository (step 113) and return to step 103 (see FIG. 2) of retrieving functions resultant from the similar functionality analysis and create a pivot table. FIG. 10 shows an example of selecting a single function and if none of the existing names are applicable, adding a new name and relating all the functions to it.

If the function name of a function or a candidate service is not the same or similar to the function name of another function or candidate service (step 109), continue to step 115 of FIG. 4 and determine if the function name is compliant with a verb and noun guide (step 115). If the function name is compliant with a verb and noun guide (step 115), and the function is using a proper pattern (step 118), keep the function name for rationalization and store in a repository, for example repository 53 shown in FIG. 1. FIG. 11 shows an example of functions that appear similar, but must not be unified nor deleted. If those functions are not synonymous and they describe different actions, then they must be considered and accepted.

If the function name is noncompliant with a verb and noun guide (step 115), and the function is not to be reanalyzed (step 116), delete the function (step 117) and return to step 103 (see FIG. 2) of retrieving functions resultant from the similar functionality analysis and create a pivot table.

If the function name is compliant with a verb and noun guide (step 115), and the function is not using a proper pattern (step 118), and the function is not to be reanalyzed (step 116), delete the function (step 117) and return to step 103 (see FIG. 2) of retrieving functions resultant from the similar functionality analysis and create a pivot table.

If the function name is noncompliant with the verb and noun guide (step 115), and the function is to be reanalyzed (step 118), return to step 108 of retrieving the functions with description and function name of FIG. 3.

Referring back to FIG. 3, if the function name of a function is the same or similar to other candidate services (step 109), and the function description of the functions (step 110) is not similar, and it is determined that the function names are not related to filters or other criteria (step 111), proceed to step 115 of whether the function name is compliant with a verb and noun guide of FIG. 4. The filters or criteria are defined as when related functions present the same functionality as another function with differences in how the functionality is performed. Theses filters or criteria may be preset or determined prior to analysis. For example obtaining an operator by name or by experience level as shown in FIG. 11. Therefore, filters are used to get information in different ways.

If the functions names are related to filters or other criteria (step 111) proceed to step 120 of FIG. 5. If there is a façade in which a function can be placed (step 120), add the function name to the façade to relate the functions under a generic term or façade (step 122) and return to step 103 (see FIG. 2) of retrieving functions and functions resultant from the similar functionality analysis and create a pivot table. Functions with common capabilities and slight variations are combined/unified and are invoked through a facade. Therefore, facades are containers of related functions that have been grouped together and will ultimately become real services. Consumers can send a request to the facade which will invoke the required function(s) as needed based on the input from the requestor.

If there is not a facade in which the function name can be placed (step 120), determine if sufficient other functions (134) and create a façade to group the functions together and store in a repository (step 121) and return to step 103 (see FIG. 2) of retrieving functions resultant from the similar functionality analysis and create a pivot table. FIG. 12 shows an example of adding a façade name that serves as a single point of access to more granular function and relating similar functions which are variations to the same façade.

FIG. 20 shows an example of using function attributes to identify and differentiate exposable functions from non-exposable functions. For example, a façade function must not be analyzed.

FIGS. 6-7 show increased detail of step 106 of FIG. 1 of differentiating exposable functions from non-exposable functions by function attributes through a functional area rationalization, for example by the exposable functions program 68. The differentiation of exposable functions from non-exposable functions by function attributes removes functions that are identified as a utility service, e.g. send e-mail notification, authentication, auditing, etc . . . ) since these functions will not be exposed as services or functions. FIG. 18 shows an example of removing functions or candidate services that were catalogued as technical operation or as a utility. The functions that are removed may be moved to a utility section and further classified.

Referring to FIG. 6, all function attributes are filled (step 123). FIG. 19 shows an example of filling all function attributes.

If the function is a business activity (step 124), and it is determined that the business activity is repeatable in the same sub-process (step 127), indicate the function as a service (step 130) and proceed to step 107 of capturing results for access by a service modeling toolkit to evaluate functions for exposure decisions. For example, “getOperator” shown in FIGS. 8-22 is repeatable task in a business process that occurs when auditing a user that processes different client requests, such as updating client data and account movements.

If it is determined that the business activity is non repeatable in the same sub-process (step 127), indicate the function as a function (step 129) and proceed to step 107 of capturing results for access by a service modeling toolkit to evaluate functions for exposure decisions.

If the function is not a business activity (step 124) and it is determined that the function is not a function from similar functionality analysis and the pivot table (step 125), the function is removed (step 128) as shown in FIGS. 17-18 and proceed to step 107 of capturing results for access by a service modeling toolkit to evaluate function for exposure decisions. If it is determined that the function is a function from similar functionality (step 125) and the function is a filter which can be part of a facade, indicate the function as a function and proceed to step 107 of capturing results for access by a service modeling toolkit to evaluate functions for exposure decisions. If it is determined that the function is not a filter which can be part of a facade (step 126), proceed step 132 of determining whether a function is reusable across different scenarios shown in FIG. 7.

Referring to FIG. 7, if the function is reusable across different scenarios (step 132), indicate the function is a service (step 130) and proceed to step 107 of capturing results for access by a service modeling toolkit to evaluate function for exposure decisions. For example, as shown in FIG. 21, “calculateTaxes” is a unique task in a business process that happens in a single event per year, although not repeatable in more business scenarios, it is important to the business due to law requirements from government and business results, as result this functions is selected as candidate service.

If the function is not reusable across different scenarios (step 132), determine whether the function is valuable to business (step 133). FIG. 22 shows an example of identifying functions that are reusable across different scenarios as candidate services.

If the function is valuable to business (step 133), indicate the function as a service (step 130) and proceed to step 107 of capturing results for access by a service modeling toolkit to evaluate functions for exposure decisions. If the function is not valuable to business (step 133), indicate the function as a function (step 129) and proceed to step 107 of capturing results for access by a service modeling toolkit to evaluate candidate service for exposure decisions. FIG. 22 shows an example of identifying whether a function which is not reusable but is considered valuable and indicating that it is a candidate service.
